Which of the following are examples of exergonic reaction?
Examples of Exergonic Reactions

- Cellular Respiration. …
- Fatty Acid Catabolism.
What are exergonic reactions quizlet?
exergonic reaction. a spontaneous chemical reaction, in which there is a net release of free energy. endergonic reaction. a non-spontaneous chemical reaction, in which free energy is absorbed from the surroundings.
Which of the following is true for exergonic reaction?
An exergonic chemical reaction is a spontaneous chemical reaction, during which the change of the Gibbs free energy is negative, and no activation energy is needed to initiate an exergonic reaction.
What is an example of endergonic reaction?
An endergonic reaction is one that requires free energy to proceed. An example of an endergonic reaction of biological interest is photosynthesis. Photosynthetic organisms conduct this reaction by using solar photons to drive the reduction of carbon dioxide to glucose and the oxidation of water to oxygen.
What is an exergonic reaction in biology?
An exergonic reaction (such as cellular respiration) is a reaction that releases free energy in the process of the reaction. … The change of Gibbs free energy (ΔG) in an exergonic reaction (that takes place at constant pressure and temperature) is negative because energy is lost (2).
What reaction is an endergonic reaction quizlet?
In endergonic reactions, the reaction gains energy and in exergonic reactions, the reaction loses energy. What are some examples of endergonic reactions? Anabolism is an endergonic reaction because the build-up of more complex molecules results in the storage of energy. You just studied 9 terms!
What is endergonic and exergonic reaction?
In an exergonic reaction, energy is released to the surroundings. The bonds being formed are stronger than the bonds being broken. In an endergonic reaction, energy is absorbed from the surroundings. The bonds being formed are weaker than the bonds being broken.
Is photosynthesis an exergonic reaction?
Photosynthesis is an endergonic (energy-consuming) process. Cellular respiration is an exergonic (energy-releasing) process.
What is an endergonic reaction in chemistry?
In chemical thermodynamics, an endergonic reaction (also called a heat absorbing nonspontaneous reaction or an unfavorable reaction) is a chemical reaction in which the standard change in free energy is positive, and an additional driving force is needed to perform this reaction.
What are examples of exergonic and endergonic reactions?
Often, one chemical reaction feeds the next and endergonic reactions are coupled to exergonic reactions to give them enough energy to proceed. For example, firefly bioluminescence results from endergonic luminescence by luciferin, coupled with exergonic ATP release.
Is glycolysis endergonic or exergonic reaction?
The overall reaction of glycolysis is exergonic. There are few stages of glycolysis which is endergonic.
Is hydrolysis an exergonic reaction?
That hydrolysis is an exergonic reaction and it yields energy. The bonds holding the phosphate onto ATP are weak. They are known as high energy bonds but not because they are strong (if they were strong it would require alot of energy to break them.
Are light reactions endergonic or exergonic?
The exergonic light-dependent reactions of photosynthesis convert light energy into chemical energy, producing ATP and NADPH. These reactions occur in the thylakoids of the chloroplasts. The products of the light-dependent reactions, ATP and NADPH, are both required for the endergonic light-independent reactions.
Is phosphorylation endergonic or exergonic?
The phosphorylation (or condensation of phosphate groups onto AMP) is an endergonic process. By contrast, the hydrolysis of one or two phosphate groups from ATP, a process called dephosphorylation, is exergonic.
Is protein synthesis endergonic or exergonic?
Protein synthesis is an endergonic process as it requires energy.
What is photosynthesis endergonic?
Photosynthesis is an endergonic process. Photosynthesis takes in energy and uses it to build carbon compounds. … Plants make carbon-based molecules from raw inorganic compounds. Plants use the organic carbon compounds as “food” and to build cell parts.
Is the Calvin cycle endergonic or exergonic?
Now we will follow the NADPH and ATP molecules as they enter the Calvin cycle. Their stored energy will be used to make sugar from carbon dioxide. These protein reactions are endergonic (have a positive delta G), and therefore require energy (from ATP and NADPH).
Is oxidation and exergonic reaction?
Is oxidation exergonic? – Quora. Generally, yes, oxidation tends to be exergonic, or spontaneous in free energy language.
What type of chemical reaction is photosynthesis endergonic?
Photosynthesis Is Endergonic
While some might think that photosynthesis is an exergonic reaction, it is not. Endergonic reactions create new chemical bonds (anabolic reactions), which store that energy until the bonds are eventually broken.
Is photosynthesis an endergonic reaction Why?
Photosynthesis is an endergonic reaction because plants cannot initiate the process of photosynthesis until they absorb light energy.
Is photosynthesis a combination reaction?
Photosynthesis is an example of a chemical reaction because it is a process in which carbon dioxide and water are combined to form glucose and oxygen. It is an endothermic reaction because it requires solar energy.
